                  NOW, THEREFORE, the parties agree as follows:

Purchaser  herewith  deposits with the Escrow Agent the amount of  $1,000,000.00
(such amount, including all income and interest thereon, is hereinafter referred
to as the "Escrow Amount").  The Escrow Agent hereby acknowledges the receipt of
the Escrow  Amount  hereby  deposited,  and the Escrow  Agent agrees to hold the
Escrow Amount for the purposes and upon the terms and conditions hereinafter set

                  2.   Distribution of Escrow Amount.
                           A.       Escrow Agent shall make the following
 distributions from the Escrow Amount to Purchaser:
                                    (i)     within 15 days after the first
anniversary hereof, 100% of all interest earned prior to such anniversary
                                    (ii)   within  15  days   after  the  second
anniversary hereof, 66_% of all interest earned between the first and second
anniversaries; and
                                    (iii)   within  15  days   after  the  third
anniversary hereof, 33_% of all interest earned between the second and third
anniversaries.
                           B. Within 10 days after the third anniversary of this
Agreement,  the Escrow  Agent  shall  distribute  the balance of the Escrow
Amount to Seller,  or such payee(s) in the United States as Seller may designate
by written  notice to the Escrow Agent  unless prior to such third  anniversary,
Escrow Agent shall have received from Purchaser a notice of claim as provided in
section 3.
                           C. If prior to such third  anniversary,  the Escrow
Agent shall have  received  such a notice of claim,  the Escrow Agent shall
continue to retain from the Escrow  Amount the  aggregate  sum specified in such
notice of claim,  and the excess,  if any,  shall be paid as provided in section
2B.





                           D.  Amounts  retained  pursuant  to  section 2C shall
continue to be held in escrow under this Agreement and shall be distributed
only in accordance with (a) an instruction signed and notarized by Purchaser and
Seller and delivered to the Escrow Agent,  or (b) an arbitration  award pursuant
to section 22 of the Stock Purchase Agreement,  a copy of which award shall have
been  delivered to the Escrow Agent,  together with a certificate  signed by the
party presenting such award and an opinion of such party's counsel  satisfactory
to Escrow Agent,  each stating that such award was made pursuant to such section
and is in full force and effect.
                           E. In no event shall the  aggregate  amount of
disbursements  made by the Escrow  Agreement  exceed  the  actual  amount of the
Escrow Amount.

                  3.       Notice of Claim.
                           If Purchaser in good faith believes that it has any
claim for  indemnification  or damages  against Seller under or relating to
the Stock Purchase Agreement or the transactions contemplated thereby, Purchaser
may  deliver to the  Escrow  Agent a notice of such  claim.  Such  notice  shall
specify  the nature of the claim and the amount  thereof  and shall be signed by
Purchaser.






                  4.  Escrow  Investments.  The Escrow  Agent  shall  invest the
Escrow Amount,  and any income and interest thereon and on reinvested income and
interest,  by (i) depositing  such amounts in interest  bearing  certificates of
deposit with the Escrow  Agent,  having  maturities of 12 months or less or (ii)
purchasing  obligations of the United States of America,  or any instrumentality
thereof and fully guaranteed thereby, having maturities of 12 months or less. In
connection with making any distributions pursuant to this Escrow Agreement,  the
Escrow  Agent may sell,  liquidate  or dispose of such  investments  as it deems
necessary to make such distributions.

                  5.  Compensation, Expenses and Liability of the Escrow Agent.
                  (a) The Escrow  Agent shall be entitled to receive  reasonable
compensation  for its  services  hereunder  as set  forth  in  Schedule  A.  The
compensation  and  expenses  of the  Escrow  Agent,  and the fees  and  expenses
incurred  in  connection  with  maintaining  the  escrow,  shall be borne 50% by
Purchaser and 50% by Seller in advance of the date on which such payments  shall
be due to the  Escrow  Agent.  The  Escrow  Agent may deduct any amount to which
Seller or Purchaser may be entitled under this Escrow Agreement any unpaid fees,
compensation  or expenses of the Escrow Agent for which Seller or Purchaser  is,
as the case may be, liable under this Section 5.






                  (b) The Escrow  Agent shall not be liable for any action taken
by it  in  good  faith  and  believed  by it to  be  authorized  or  within  the
discretion, rights or powers conferred upon it by this Escrow Agreement, and the
Escrow Agent may rely and shall be protected in acting or refraining from acting
in  reliance  upon the  opinion of counsel or upon any  certificate,  request or
other document believed by it to be genuine and to have been signed or presented
by the proper party or parties.  The Escrow Agent shall not be obligated to make
any inquiry as to the authority,  capacity, existence, or identity of any person
purporting  to give any such  certificate,  request  or other  document.  If the
Escrow  Agent shall  become  involved in any  litigation  by which  Seller shall
contest any claim by Purchaser  against the Escrow  Amount,  the Escrow Agent is
authorized to comply with any final order or decree duly entered by any court of
competent  jurisdiction  in any such  litigation.  Purchaser and Seller agree to
indemnify the Escrow Agent against,  and to hold the Escrow Agent harmless from,
any and all loss,  damage or  liability,  and all  expenses  (including  without
limitation legal fees), except to the extent arising out of the gross negligence
or willful misconduct of the Escrow Agent,  incurred by the Escrow Agent arising
out of or in  connection  with the  execution,  delivery or  performance  by the
Escrow Agent of this Escrow Agreement.  The Escrow Agent shall not be liable for
any investment  losses  resulting  from the  investment,  reinvestment,  sale or
liquidation  of any  portion of the  Escrow  Account,  within  the  agreed  upon
investments as referred to in Section 4, "Escrow Investments."






                  6.  Resignation  of the Escrow  Agent.  The  Escrow  Agent may
resign and may be discharged from any further duties or obligations hereunder by
giving at least 30 days prior written  notice of such  resignation  to Purchaser
and Seller.  On the effective date of such  resignation,  the Escrow Agent shall
pay the Escrow  Amount to such  successor  escrow agent as Purchaser  and Seller
shall have  designated in a notice  delivered to Escrow Agent or, in the absence
of such notice, to the Clerk's Office of the United States District Court of the
Eastern  District of New York or of the New York State Supreme Court for Suffolk
County.
